ANSI B16.9 Carbon steel Buttweld elbow

ANSI B16.9 SCH40 STD elbow is one of the most widely used pipe fittings in carbon steel pipe fittings. ANSI B16.9 SCH40 STD Elbow Elbow is made by cutting the steel pipe into pipe sections according to the requirements, putting it into the intermediate frequency pushing furnace, and heating and pushing it.
The main function of the ANSI B16.9 SCH40 STD elbow is to combine with the steel pipe or flange at the turning point of the pipeline system to connect two pipes of nominal diameter, so that the pipe can be 90°, 45°, 180° and various degrees. 's turn. Change the direction of the pipe. The nominal pressure is 1-1.6Mpa.
Due to the good comprehensive performance of ANSI B16.9 SCH40 STD elbows, carbon steel elbows are widely used in water, beverages, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizers, shipbuilding, waterproofing, etc. A large number of elbows are used in the pipeline system, which can be divided into 15, 30, 45, 60, 90, 180 points according to the angle, of which 45°, 90°, and 180° are the most commonly used.
    When using, according to the construction requirements, at the turning point of the pipeline 1: Directly weld the elbow to the pipeline. 2: Weld the Flanges on both ends of the elbow evenly, and connect them with Bolts to make the whole pipeline integrated and start working normally.
  ANSI B16.9 SCH40 STD elbow is the most widely used pipe fittings in basic engineering piping systems and equipment such as chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other basic engineering.
Our ANSI B16.9 SCH40 STD Elbow Carbon Steel Pipe Fittings are standardized in materials, finely processed and priced in line with market demand. According to the needs of different markets and different customers, special shaped manufacturing can fully meet the requirements of customers and markets for different flanges. And we will inform customers of market needs so that they can quickly expand the market.
Types of ANSI B16.9 SCH40 STD Elbow:
According to the standard can be divided into: ANSI B16.9 SCH40 STD elbow
According to the pressure, it can be divided into: STD, Sch40,
According to the process, it can be divided into: pushing, pressing, forging,
According to the material can be divided into: ASTM/ASME A234 WPB, WPC
According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, ie R=1.5D; short radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, ie R=1.0D. (D is the diameter of the elbow, and R is the radius of curvature).

Production Process of ANSI B16.9 SCH40 STD Elbow
1: Cut high-quality steel pipes into segments by sawing machine according to product requirements, place them on a push-making machine, heat them in an intermediate frequency furnace, push-shape them, and put the formed elbows into a press machine for shaping.
2: Pass the shaped elbow blank through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on the two ends of the elbow blank, with a certain angle and a certain edge, and the angle and deviation range are strictly in accordance with the requirements of the drawings.
3: Put the elbow blank after shaping and beveling, and put it into the shot blasting machine for shot blasting on the surface of the pipe to remove the iron oxide scale on the inner and outer surfaces.
4: The finished elbow product will be inspected according to the requirements of the drawing for the thickness and the radius of the bend.

5: Type the qualified elbow on the end face according to customer requirements, including size, steel number, batch number, and identification. And according to customer requirements, the elbows are treated with anti-rust treatment, 1: paint, 2: anti-rust oil, and then put them into wooden boxes or wooden pallets for transportation.
